我是靠谱客的博主 称心柚子，这篇文章主要介绍tp5.1 php 拼装/组装一维 二维 多维数组 foreach循环$useridarr[]=$v['user_id'];另一种办法：array[{id:1,titl:标题1},{id:2,titl:标题2}]，现在分享给大家，希望可以做个参考。

另一种办法：array[1,2,45]
foreach for循环组装成一维数组
$useridarr[]=$v['user_id'];
另一种办法：array[{id:1,titl:标题1},{id:2,titl:标题2}]

$uidarr输出：array[1,2,45]
$uidtitlearr输出：array[{id:1,titl:标题1},{id:2,titl:标题2}]

其它学习点：
输出字符串：
